Hi
I am a leatherworker and typically use pre 1960’s sewing machines at slow speeds normally about 500 rev per min or far lower
Obviously many parts were made by foundary and are no longer available, but we can make 3D drawings of the parts typically small gears using Fusion 360
My question is what is the best metal to use to make copies of these gears and other small parts, i dont expect any parts to be heavily stressed, but wear may be a issue
Regards and thanks
Chris
